Replacement vacuum shut-down switch for Englander pellet stoves. Fits the following models:

NOTES: 

1. This will retro-fit to older (metal) type switches in older Englander pellet units. 
2. Units made before 2004 that have a vacuum switch use this PU-VS switch.
3. In 2004, a door ajar switch was added; that switch is # CU-VS. The CU-VS hose connects to the back of the firebox and the PU-VS hose connects to the exhaust blower. Both switches were used until SN 150,000, which then only used 1 CU-VS switch and not this PU-VS switch.
